I suspect the programme you are referring to was actually the excellent All Our Yesterdays (The World At War didn't come on until 1973).
It was Brian Inglis and All Our Yesterdays that woke me to the reality of war. We would watch it every week (I think on a Sunday) and I used to think how lucky we were to be living in an age when such things couldn't happen anymore. I still remember the day when I asked my parents what was stopping world wars happening again? Even as the question left my lips the shocking reality hit me: nothing. I was probably about 7 or 8 years old, it haunted me for weeks afterwards.
Ian, many thanks for the correction, seems I was inadvertently spreading fake news..again..Duh..! By 1973 I was married and in the process of buying my first flat..
TBM, I suspect doctors appointments system is not a lot different anywhere and unlikely to improve....? It would seem a very long shot, but given the situation as you describe it, perhaps a call to your local MP might just get you seen at least.
